## Specification Compliance Guidelines

### How to Ensure Specification Adherence

1. **Before Each Phase**: Complete the Pre-Implementation Specification Gate
2. **During Implementation**: Reference specific SDD sections in each task
3. **After Each Task**: Run Specification Compliance checks
4. **Phase Completion**: Verify all specification requirements are met

### Deviation Protocol

If implementation cannot follow specification exactly:
1. Document the deviation and reason
2. Get approval before proceeding
3. Update SDD if the deviation is an improvement
4. Never deviate without documentation

## Metadata Reference

- `[parallel: true]` - Tasks that can run concurrently
- `[component: component-name]` - For multi-component features
- `[ref: document/section; lines: 1, 2-3]` - Links to specifications, patterns, or interfaces and (if applicable) line(s)
- `[activity: type]` - Activity hint for specialist agent selection

---

## Context Priming

*GATE: You MUST fully read all files mentioned in this section before starting any implementation.*

**Specification**:
- `docs/specs/013-employee-scheduling/product-requirements.md` - Product Requirements (15 Must Have features + 4 Should Have)
- `docs/specs/013-employee-scheduling/solution-design.md` - Solution Design (Syncfusion integration, DB schema, APIs)
- `docs/specs/013-employee-scheduling/overtime-presets.json` - Jurisdiction overtime rule library
- `docs/specs/013-employee-scheduling/overtime-presets.md` - Overtime presets documentation

**Key Design Decisions**:
- **ADR-1**: Use Syncfusion EJ2 Schedule for calendar UI (not custom implementation)
- **ADR-2**: Timeline Week view as primary with employees as resources (rows)
- **ADR-3**: Syncfusion Community License (free for <$1M revenue / ≤5 developers)
- **Provider Architecture**: BuyerKioskSchedule extends existing ScheduleProvider abstract class
- **Database**: Store-specific tables for shifts/punches/timesheets, Central DB for overtime rules and pay rates
- **Naming Convention**: camelCase for all columns except timestamps (snake_case: `created_at`, `updated_at`, `deleted_at`)

**Implementation Context**:
- Commands to run:
  - `./test.sh` - Run all tests
  - `./test.sh --testsuite unit` - Run unit tests only
  - `./test.sh --stan` - Run tests + PHPStan analysis
  - `php userfrosting/conductor run` - Run database migrations
  - `cd userfrosting && composer install` - Install PHP dependencies
- Patterns to follow:
  - `userfrosting/src/BuyerKiosk/Workbook/WhenIWorkSchedule.php` - Reference provider implementation
  - `userfrosting/src/BuyerKiosk/Workbook/ScheduleManager.php` - Provider resolver pattern
  - `userfrosting/migrations/input/` - Migration JSON format
- Interfaces to implement:
  - `userfrosting/src/BuyerKiosk/Workbook/ScheduleProvider.php` - Abstract provider interface

## Critical Path

The minimum path to a functional scheduling feature:

1. **P1** → Database tables (foundation)
2. **P2** → BuyerKioskSchedule provider (enables panel integration)
3. **P3** (ShiftRepository only) → Shift CRUD data layer
4. **P4** (SchedulingController + Syncfusion) → Admin can create schedules
5. **P6** (TimePunchController modification) → Employees can clock in/out

Timesheet system (P5) can be delivered as a fast-follow after core scheduling is live.
